Peavey Classic 20 Mini Guitar Amp Head


The Peavey Classic series of amplifiers have been incredibly popular with guitarists all over the world for its period accurate vintage clean and crunch vibes. This mini 20w head version of this amazing amplifier offers up all of the tone of its big brothers but with a few added tweaks that make it more usable both at home and in the studio.

Sweet Tones

Using an all tube preamp and poweramp circuit the Classic 20 can go from crystal cleans to a dirty crunch perfect for blues rock. These tones are spread wonderfully over two channels that are controlled with a shared EQ and reverb but different volume controls.

On channel 1 you just have a single volume control set at an ideal input gain so your get the most clean headroom possible out of this little amp. Channel 2 however has both a pre and post gain section that lets you get those dirty and crunchy tone we all love.

Best of all you can get these tones anywhere thanks to the 3 position attenuator which can take the amp down from 20w to 5w or 1w.

Digital Spring Reverb

With the head being so small you can't really fit a full spring reverb unit inside. So Peavey instead opted to use a high quality digital circuit for the reverb that carefully replicates a traditional spring circuit for a sound that gets as close as possible to the real thing.

Simulated Output

Across their micro amps range Peavey have introduced their MSDI circuit. This circuit not only has a mic simulated output via XLR, USB and 3.5mm jack but it also features a speaker defeat switch. When engaged the amplifier doesn't require a cabinet to run safely so you can just run this straight in to your audio interface or mixer for cab-less playing. Not only great for keeping the noise down at home but also reducing stage noise live.

Finishing off the cool new tech out also have a pair of T.S.I. or Tube Status Indicators on the front which constantly monitor your power amp valves and will let you know when they need changing.

Here's what Peavey say about the Classic 20 MH

Revered by blues, country and rock players alike, Peavey Classic amps span the tonal landscape from vintage to contemporary with ease, and the Classic 20 MH provides that tone in a highly portable package. The all-tube, 20-Watt Classic 20 MH is powered by two EL84 power tubes and 3 12AX7/ECC83 preamp tubes. It has two channels that follow the same gain structure and voicing of the Peavey Classic series amps for pure and versatile tone. The channels share a three-band EQ, lush reverb and an effects loop. The channels, effects loop and reverb are all footswitchable. Peavey's TSI tube monitoring alerts players of power tube status, and in the event of a necessary tube replacement, identifies which tube needs to be replaced. Rear panel features such as a Microphone Simulated Direct Interface (MSDI) with XLR output and USB out, speaker defeat switch and 3 position power attenuator switch make the Classic 20 MH mini head perfect for studio environments.
